No Tuskegee Pilot Downed Nine German Fighters
The movie credits Lincoln Scott with 9 fighters destroyed in 30 missions.
In fact, none of the Tuskegee Airmen were officially credited with even five kills. The most likely ace was Lt. Lee "Buddy" Archer (no confusion with the Archer in the movie). The real Archer's score was 4.5 kills. I believe today he has been credited with five kills and given official ace status, though he has not seen much reason to make a statement about it. Yes, it was racism that kept Archer and others from being credited with five or more kills. Furthermore, bomber escort was more important to the Tuskegee Airmen than shooting down planes. That is how they "never lost a bomber to enemy air attack," and also means the dogfight scene in the movie probably didn't happen. But the pilots were not assigned bomber escort duty until June 1944, less than a year before the war ended. Still, they destroyed 409 German aircraft (in comparison, the highest-scoring 56th FG destroyed over 1000 planes).
Ace pilots were a minority of the Airmen who flew against the Germans and Japanese in WWII. But I've seen where movies today give out liberal kill tallies to fictitious pilots, as if to say the more kills, the better the pilot. Many times, a pilot never even saw an enemy aircraft on a mission. These men did a lot more than just shoot down planes. And by the way, some of the planes they destroyed never left the ground. They also shot up and bombed railroad cars, moving vehicles, roads and bridges. Most importantly, they provided air superiority. It was tremendous for a soldier or sailor to know, especially during an invasion like Normandy or Okinawa, that every plane in the sky that day was "one of ours."
